Synchronizing local time with an external source
Complete the following steps to synchronize the local time of the principal or
primary FCS switch with that of an external NTP server.
1. Log in as admin .
2. Enter the
tsClockServer ipaddr
command.
The ipaddr variable represents the IP address of the NTP server that the switch
can access. This argument is optional; by default, the value is "LOCL".

Correcting the time zone of a switch
If the time of your switch is off by hours (and not minutes), use the following
procedure to set the time zone.
1. Log in as admin .
2. You can use the
tstimezone --interactive
command and follow the prompts
or enter the tsTimeZone command as follows:
tstimezone [houroffset [, minuteoffset]]
For Pacific Standard Time, enter tsTimeZone -8,0
For Central Standard Time, enter
tsTimeZone -6,0
For Eastern Standard Time, enter
tsTimeZone -5,0
The default time zone for switches is universal time conversion (UTC), which is 8
hours ahead of Pacific Standard Time. Additional time zone conversions are listed
in Table 5. The parameters listed do not apply if the time zone of the switches has
already been changed from the default (8 hours ahead of Pacific Standard Time).
For more information about the command parameters, refer to the
tsTimeZone
command in the Fabric OS Command Reference .
Setting the time zone needs to be done only once, because the value is stored in
nonvolatile memory. For U.S. time zones, use Table 5 to determine the correct
parameter for the
tsTimeZone
command.
